WALL-BONDING DEVICE.

Application filed August 13, 1923. Serial No. 657,116.

To all whom it may concern:

Be it known that 1, JAMES H. lVAUGH, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in all-BondingDevices, of which the following is a specification.

This invention relates more specifically to a device for bondingtogether the members of a hollow concrete wall.

A main object of the invention is to provide a bonding device designedto be employed in connection with slip forms for bonding the members ofa hollow concrete wall together as the wallis poured.

A further object is to provide a bonding device carrying a plurality ofbonding members that may be positioned on the opposing faces of a pairof hollow wall members and utilized with a wall slip form during thepouring of the wall members.

A still further object of the invention is to provide a novel concretewall slip form, in which the wall bonding device constitutes a portionof the form.

Other objects and advantages will be apparent from the followingdescription, reference being had to the accompanying drawing, in which:

Fig. 1 is a plan view of my bonding device illustrated in connectionwith a slip form mold in operative position on a hollow concrete wall. 7

v Fig. 2 is a transverse vertical section of the same taken on line 2,-2of Fig. 1, look- .ing in the direction indicated by the arrows.

Fig. 3 is a perspective view of a portion of a concrete wall showing therelation of the bonding device.

Fig. 41- 'is a detail perspective view of the upper end of a bondingstrip, showing a portion of a bonding rod secured thereto.

This invention is designed to be employed in connection with concreteslip forms of the type illustrated in my co-pending application for U.S. Letters Patent entitled Apparatus for constructing concrete walls, S.N. 587,894, filed September 13, 1922.

In the above entitled application the slip form was designed for forminga singlev solid concrete wall, while the form constituting a part of myinvention is adapted for the formation of a hollow concrete wall,

the construction being altered to conform to my novel wall bondingdevice which is employed in conjunction therewith.

Mold walls for forming the hollow wall are arranged in pairs l0, l1, and12, 13, each pair being spaced apart between which the concrete ispoured to form the wall mem bers 1e, 15, the space between the pairs ofmold walls being filled with an insulating material, such as groundcork, in the construction of ice houses, or other refrigeratingstructures. lValls 11, 12, are rigidly connected together by means oflongitudinally extending beams 16, 17, 18, spaced apart, whilethe outerfaces of mold walls 10, and 13, have similar beams 19, 20, 21, securedthereto. Bolted or otherwise secured to the outer faces of beams 19, 20,21, are a plurality of vertically extending beams 22, 23, spaced apart asuitabledis tance, the upper ends of said beams extending upwardlybeyond the upper edge of the mold walls and each oppositely disposedpair are tied together with laterally extending timbers 24, 25, spacedapart. Disposed upon the upper edges of the mold walls are a number oftransversely extending beams 26 spaced apart and their ends extendingbeyond the outer faces of vertically extending beams 22, 23, a suitabledistance to form a support for a platform flooring 27 for the workmen.Inclined braces 28 are provided to tie beams 26, to the lower end ofbeams 22, 23. A. railing 29 is secured along the outer edges of theplatforms to insure the safety of the workmen, during the constructionof the hollow wall.

Mounted in the foundation 30 of the hollow wall are a plurality ofvertically disposed reinforcing rods 31, 32, the rods ex tendingupwardly through each wall member to approximately slightly greater thanthe entire height of the finished wall, and which for convenience in thehandling may be formed in sectional lengths. The rods pass throughexteriorly threaded sleeves 33, 34, mounted in threaded bearing blocks36, secured between the cross timbers 2%,

25, secured, to the upper ends of the vertical beams 22. 23, of the slipform. The lower ends of sleeves 33, 34, beanagainst blocks 37, 38,capable of being rigidly secured to each of the rods 31, 32, and theirupper ends are each provided with a toothed wheel 39, for rotating thesleeves to eievate the form as the work progresses. In order tostrengthen the form construction, vertically disposed tie rods 40, aresecured between beams 19 and blocks 11 mounted between the cross timbers21-, 25, and a plurality of vertical tie rods 43 are secured betweenbeams 16, 18, and cross bars at secured to the top of the form walls andspaced apart as clearly shown in Fig. 1 of the drawings.

The improved bending device preferably consists of a plurality of pairsof vertically disposed timbers or wood strips 4:5, 4:6, approximately 1"X 3". Hounted in each pair of timbers 45, 46, are a plurality of wallbonding rods 48, which pass through aper tures 19 formed in the timbers,their ends terminating beyond the outer faces of the timbers -15, 46,and the vertically disposed rods 31, 32, as clearly shown in Figs. 2 and3 of the drawings. The ends of bonding rods 18 are upturned as at 50,and horizontally disposed reinforcing rods 51 are mounted on the crossrods, the upturned ends of said cross rods preventing a displacementwhile pouring the concrete.

The timbers or wood strips carrying the bonding rods 48 are disposedagainst the opposite faces of the Wall members and spaced apart asuitable distance as shown in Fig. 1 of the drawings.

In order that the bonding devices will not interfere with the operationof the slip forms, each of the inner oppositely disposed mold walls 11,12, are provided with a plurality of vertically disposed slots oropenings 55, of approximately the same width as the wood stJips it-5carrying the bonding rode, the strips chambering in the openings formedin the mold walls. By means of the above construction it will be notedthat the bonding devices may be placed in position before work .on thewall is commenced, the vertical rods 31, 32', and the horizontallydisposed bonding rods 51 maintaining the devices in proper spacedrelation, as the Work proceeds. As the strips carrying the bonding rodscompletely fill the slots formed in the mold walls, no leakage of thewet concrete will occur during the pouring operation.

In the operation of my bonding devices the slip forms are placed overthe concrete foundations 60, and then the plurality of pairs of bondingdevices are placed in the slots formed in the mold walls 11 and 12. Thevertical reinforcing rods 31 being in position the horizontalreinforcing rods 51 are placed on the upturned ends of the bonding rods48, as clearly shown in Fig. 3 of the drawings. As the wall members ofthe hollow wall are poured it will be seen that the bonding devices willsecurely bond the memhere together. After the poured portion of themembers has set a sufficient time the slip form is moved upwardly bymeans of the toothed wheels The above operation is continued until thewall is completely linished, the slots in the side walls 11 and 12permitting an up ard movement of the slip form without interfering inthe slightest with the bonding device, and moreover as the wood strips45 completely fill the slots formed in the side walls 11 and 12, noleakage of the wet concrete from the slip form will occur.

From the above description it will be noted that I have provided a novelform of bending device which may be effectively used in connection withconcrete slip forms, and furthermore it may be used advantageously withstationary concrete forms.

As the strips 15 are thin, they may be left against the inner faces ofthe wall member or they may be removed therefrom without disturbing thebonding rods l8, saw slots 62 being formed in side strips from one sidete each of the apertures.

What I claim is- 1. In a bonding device for hollow concrete walls, aplurality of vertically disposed wooden strips arranged in oppositelydisposed pairs and spaced apart, and a plurality of bonding rodsconnected to each pair of said wooden strips, the ends of said rodsprojecting beyond the outer faces of said strips, the pairs of woodenstrips being removable from the bonding rods after the formation of thehollow wall members.

In combination with concrete slip forms for forming hollow concrete wallmembers, said forms being provided in their oppositely disposed wallswith a plurality of vertically disposed slots, of a plurality ofelongated members arranged in pairs each pair being oppositely disposedand provided with a plurality of transversely disposed bonding memberssecured thereto, said elongated members being disposed in the slotsformed in the mold walls of said mold forms, the ends of the bondingmembers projecting into the mold. forms, whereby the operation of theslip form will not interfere with the bonding members, and means to movesaid slip forms.
